Detailed DescriptionThe SoShaderProgram class is used to specify a set of vertex/geometry/fragment objects​. This node can store one of each of SoVertexShader, SoGeometryShader and SoFragmentShader in its shaderObject field​. Coin will load all shader objects specified there, and attach all objects into a program before binding it as the current shader program​. See Shaders in Coin for more information on how to set up a scene graph with shaders​. FILE FORMAT/DEFAULTS: ShaderProgram { shaderObject [] } See also SoShaderObject SoShaderProgram Since Coin 2​.5

Member Function Documentation

SoType SoShaderProgram::getTypeId (void) const [virtual]Returns the type identification of an object derived from a class inheriting SoBase​. This is used for run-time type checking and 'downward' casting​. Usage example: void foo(SoNode * node) { if (node->getTypeId() == SoFile::getClassTypeId()) { SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type } else if (node->getTypeId()​.isOfType(SoGroup::getClassTypeId())) { SoGroup * group = (SoGroup *)node; // safe downward cast, knows the type } }For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses​. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through for instance Inventor/nodes/SoSubNode​.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine​.h (for engine classes) and so on​. For more information on writing Coin extensions, see the class documentation of the toplevel superclasses for the various class groups​. Implements SoBase​.

const SoFieldData * SoShaderProgram::getFieldData (void) const [protected], [virtual]Returns a pointer to the class-wide field data storage object for this instance​. If no fields are present, returns NULL​. Reimplemented from SoFieldContainer​.

void SoShaderProgram::setEnableCallback (SoShaderProgramEnableCB * cb, void * closure)Adds a callback which is called every time this program is enabled/disabled​.

void SoShaderProgram::GLRender (SoGLRenderAction * action) [virtual]Action method for the SoGLRenderAction​. This is called during rendering traversals​. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method​. Reimplemented from SoNode​.

void SoShaderProgram::search (SoSearchAction * action) [virtual]Action method for SoSearchAction​. Compares the search criteria from the action to see if this node is a match​. Searching is done by matching up all criteria set up in the SoSearchAction -- if any of the requested criteria is a miss, the search is not deemed successful for the node​. See also SoSearchAction Reimplemented from SoNode​. References SoMField::getNum(), SoAction::getPathCode(), SoSearchAction::isFound(), SoAction::popCurPath(), SoAction::pushCurPath(), SoNode::search(), and shaderObject​.
